javascript - 错误: ETIMEDOUT on NPM usage in Meteor

Question

我尝试使用this Meteor 1.3.2.4 中的 NPM 包。它在函数中使用 eventemitter 并具有异步回调。我尝试使用基于 this guide article 的 Meteor.bindEnvironment 将其转换为同步外观。如下所示:

Meteor.methods({
    proxyFetcher() {
        console.log("OK run");
        var options = {
            protocols: ['http'],
            anonymityLevels: ['elite'],
            sourcesBlackList: ['bitproxies', 'kingproxies']
        };

    var gettingProxies = ProxyLists.getProxies(options);
    Proxies.remove({});

    gettingProxies.on('data', Meteor.bindEnvironment(function(proxies) {
        console.log(proxies.length);
        proxies.forEach((proxy) => {
            Proxies.insert({proxy: proxy.ipAddress + ":" + proxy.port});
        });
        // Received some proxies.
    }));
}
}

但这是我的输出:

正如您所看到的，服务器重新启动并且我的代码在经过一些迭代后返回错误。 问题是什么以及将此包与 Meteor 一起使用的正确方法是什么。

大概是 proxy-lists 发出的一个 http 请求失败了，并且这个错误没有被捕获，所以它正在冒泡，导致整个 Node 进程崩溃。

如果您处理了错误，应该可以防止它使进程崩溃:

gettingProxies.on('error', function(error) {
    // Some error has occurred.
    console.error(error);
});
